How do I stop a contact form being processed if a condition applies?

[john8m]

I want to be able to prevent my simple contact form from being processed if a "hidden" field has been filled in (to prevent spam).

 

I'm going to hide the field with css so human users don't fill it in. I've searched and searched for this with no luck! (new to php by the way)

 

Thanks in advance

Use javascript to validate the form than act based on javascripts results.

<?php

if ($_POST['hidden_field']!='') {
 //do not process form
} else {
 //process form
}


?>

Not reliable - easily circumvented by turning off javascript. Program your PHP check, then add javascript overtop to improve functionality for the user.

That worked a treat.
